Everyday Objects:
* Balloons: Filled with helium or air.
* Tires: Filled with compressed air.
* Soda bottles: Contain carbon dioxide gas.
* Cans of spray paint: Contain pressurized gas.
* Aerosol cans: Contain compressed gas to propel the product.
* Lighters: Contain butane gas.
* Gas stoves: Use natural gas or propane.
* Refrigerators: Contain refrigerants, which are gases.
* Air conditioners: Use refrigerants, which are gases.
Natural Objects:
* The atmosphere: A mixture of gases, primarily nitrogen and oxygen.
* The Sun and stars: Made up primarily of hydrogen and helium gases.
* Planets: Some planets have atmospheres made of gases, like Mars and Venus.
* Clouds: Made up of water vapor, which is a gas.
* Volcanoes: Erupt gases like sulfur dioxide and carbon dioxide.
* Geysers: Powered by underground steam.
* Natural gas deposits: Found underground.
Other Objects:
* Gas tanks: Used to store and transport gases like propane, butane, and natural gas.
* Gas pipelines: Transport natural gas over long distances.
* Gas cylinders: Used for welding, diving, and other industrial applications.
* Gas chromatographs: Scientific instruments used to separate and identify gases.
Important Note: Many objects contain gas in a *dissolved* form. For example, water contains dissolved gases like oxygen and nitrogen. This gas isn't in the same way as gas in a balloon, but it is still present.
